macros: Add remaining restrictions for follow-set restrictions
Adds the remaining restrictions for follow-set ambiguities in macros.
This means adding the remaining allowed tokens for all fragment
specifiers with follow-up restrictions, as well as handling allowed
fragment specifiers in certain cases. For example, :vis specifiers can
sometimes be followed by fragments, if they have the :ident, :ty or
:path specifier. Likewise for :path and :ty which can be followed by a
:block.
Finally, we also allow *any* fragment after a matcher: Since the matcher
is delimiter by parentheses, brackets or curlies, anything is allowed
afterwards.
